Sorry for the lack of information. The archives are .rar 200MB each (5 all together). I right clicked the last archive and selected “extract here”, the extracting window popped up for less than a second then vanished without extracting anything. No error messages at all. Thanks.

is there possibility for you to check if same archive works on 32bit windows?

need to see if it is due to shell ext, or something specific to archive?

@Kai:
Yes, this did not help.
But after reinstalling PA11, I do not see the error anymore.
The German option now works flawlessly (without setting to English).
Therefore, uninstalling and reinstalling PA11 somehow fixed the bug for me.
it seems that language was not set in registry at all, hence it didnt know what to use for sfx.
